Abstract
An image recording apparatus including a pattern forming device for forming a light-shielding pattern on one of opposite surfaces of a photosensitive recording medium. The light-shielding pattern is formed of a light-shielding material which is capable of shielding a radiation. The apparatus further includes an exposing device for irradiating the above-indicated one surface of the recording medium, and thereby forming an optical latent image which corresponds to the light-shielding pattern. The light-shielding pattern is removed by a cleaner from the recording medium after the optical latent image is formed. The optical latent image formed on the medium is developed into a visible image.
